Patented Mar'. li, l'il To all whom 'it may concern.'

lle it known that l, .lonx S. Ln'ron, a citizen ot' the UnitedL States,and a resident of Anderson, in the county of Madison and tate ofIndiana, have invented a new and improved Raising Device for Molds, ofwhich the following'is a full., clear, and e2;- :ict description.

My invention relates to a raising device for molds employed for makingconcrete walls or the like having reinforcing 'oars therein, and has forits object to provide device tor building a reinforced wail concrete orthe like, the 4mold thereof being adapten to be raised from ausl overthe concrete wall after the same has sntiiciently set, and constitutingthe torni for a second section of the saine wall, and so on upwardlyuntil the said wall is completed to the tlcsirecl height.

An embodiment or my invention comprises a tranne secured to a niolcl forconcrete Walls or the like having reinforcing bars therein, :Lworkingplattform secured to the said trame, and means for raising thesaid mold to a desired height over a finished Woll, previously formed bythe said molti, preparetory to molding another portion ot' the said wallover the same and forming a part thereof, with tno seid mold, which israised after erich succeeding Wall portion has snnlciently set, untilthe desired height of the said wall formed by the combined mold portionsmolded one wall7 is reached.

lviy invention still further embodies certain novel features ofconstruction, as will be hereinafter more fully described and particularly set orth in the appended claim. Reference is to be had to theaccompanying drawings, forming a part of this specitication', in whichsimilar characters of reference indicate corresponding parts in all theviews, and in which Figure 'l shows a plan view oi' my invention asapplied; Fig. Q is a sectional side elevation or' the saine; Fig is anenlarged detail sectional view, parte being broken awa showing themea-ns for raising the mol 5 Fig. 4 is a sectional plan View taken onthe line i-l in Fig. 3; Fig. 5 is a plan View of the jack head; F ig. 61s a plan view of the clutch showing the removable cover thereof; Fig. 7is a View of the same with Athe cover removed; and F ig. 8 is asectional View taken on the line 8--8 in F ig. 3, showing the concaveclutch ,members with afreiniorcing bar therebetween.

A inolcl l0 isprovided, comprising sides ll, and secured thereto bymeans ot braces l2 and. fastening members 13, is e iranie- 'vvork 14.The framework le comprises ver tical members l5 and suitable tliagorml`braces 16, and secured to the saicl 1 C worlr l-l is e working platform17, heli. horizontal position on the framework ltby a brace 1S. A crossplate 19 is rcvirlei, l

secured to the framework fl, an" seen to 'the said framework by suitablebolts, l a jack heeel 20. A hollow raising screw 2' is slipped over areinforcing bar 22 need 'for strengthening the wall, and secured to thescrew 2l 'is a ratchet 23 engaged. by n reversible pavvl 24, the' wholeconstituting a lifting jack 25, having a handle thereon for operatingthe saine. A. locking clutch 27 is (provided, tnrnably helcl on thescrew,

Q1 an having therein oilset concave toothed wheels 28, adapted to engagethe reinforcing bar 22 'and securely grip the same to prevent the moldand framework from slipping downward thereon. Springs 29 are secured tothe sioles of the clutch 27 end. help-thc wheels 28 'to grip thereinforcing bar. 22, and a removable cover 30 comprising similar pertslis bolted to the clutch 27. The wheels 28 are preferably concave toenable the saine to more easily grip the reinforcing bar The raising.,`jack 25 is equipped with a spring 32 engaging the pawl 24 fior holdingthe saine Ain engagement with the ratchet 23, as Will be easily seen byreferring to Fig. 3.

The operation ot` my device is as iollows: The reinforcing bar 22 isplaced in the mold 1l, and the raising jack 25 and parts thereot arearranged as shown in Fig. 2. Concrete is then ooured into the mold antiallowed to harden. l/Vlien the concrete `has suificiently set, the jack25 is operated and forces the mold to move upwardly, the head 20 `yeingsecured to the framework 15 of the mold 1l and being screw-threadedtherein for engagement with the ,raising screw 21. When the, mold hasbeen raised to such a height that the lower part of the mold stillcovers the 'ripper part or" the linished Wall, the precise o eration asheretotore described is repeater ,and in this way an entire well can. beeasily formed with one mold, the said Wall when finished having theappeamnce of. one complete wall. The locking clutch 27 pi'evens anydown.- wad 'movement and the Wheels Q8 seeiu'ely grip 'die i'einfeieingbei" `Wlien the Well is completed the reinfo'feiiig bei is eut eli? atthe top, the mold and raising device be ing ready te be used teeenetmei; :mother Well.

It will be undelsood that any number of raising jacks can be used en onemold, depending only on the length of the Wall. It will be Still furtherunderstood het the misinijaek 25 is reversible and should the jack lieud20 and the lockin clutch 27 come within close proximity et each other,the Said jack 25 can be operated te separate them by ineens of thereversible Spring-actu ated pawl 24 en 'the jack 25.

Having thus described my invention, I claim as new and desire to secureby Letters latent:
